Electron Microscopy and Spectroscopy Laboratory

The Electron Microscopy and Spectroscopy Laboratory (EMSL) at the Institute of Nanotechnology (INT) at the Karlsruhe Institute of Technology (KIT) focuses on structural and compositional characterization at the atomic to nanometer scale, providing a direct bridge between synthesis/processing and properties/functionalities of materials for target oriented materials research and development.
